Some of you may have noticed a change to the Wildlife@Home video watching interface over the last few days. Now when you view a video you may see something like this. The timeline below the video now shows where the background subtraction algorithms detect foreground motion. This process is markedly better on the tern and plover videos due to the large amount of foliage movement around the grouse nests. Hopefully these timelines will help the video classification process.

It would be much more useful if the width of the background subtraction matched the width of the video progress bar - not because we can skip ahead but as a warning that something was detected by the algorithm.

Almost none of the timings I've seen correspond to the video timing - often they are hours apart.

Mouse-over on the timeline brings up an info box. Everything is "unspecified". Is this a future feature whereby the algorithm detects actual behavior?

Hopefully we can get our algorithms to detect behavior, but right now simple presence or motion of a bird is proving to be quite difficult (although that was expected).

Kyle should have an update to the interface soon where you can click on the timeline to be taken to the beginning of a segment with motion in it. Should really speed up watching videos (at least for the ones without significant wind).
